    Phoronix: A Look At Why Linux Graphics Drivers Have Issues

    Here's an interesting look at the state of the Ubuntu bug count as it concerns Linux graphics driver issues...

    donate Intel hardware to Intel engineers?

Instead of shitting here, go work and donate money/hardware to them. How about that? Or you start trolling again how bad things are NOT?
    So, now we have to donate Intel hardware to Intel engineers?

So switching between one non working shit and another non working shit is not an issue. The issue is a LACK of tearing free desktops and LACK of completely tearing free video playback and LACK of real sync to vblank in any configuration. Period.

    I have better idea

    graph

    This is a development workflow graph, it's not a metric and should not be used to compare quality between drivers. There are several parameters used for generating this graph which make it completely irrelevant for drawing any conclusions about anything you end users care about.

    To the questions about the color palette, it is auto generated.

    To the questions about 8xx; those chips are partly supported upstream but are not supported in Ubuntu thus no bugs in those architectures pertain to data shown in this graph.

    Well I could write and maintain a KMS driver for it :-)

    Not a chance. If you look at the source, the i810 driver is in a folder called "legacy". It will not be getting any new features. Which means you get basic modesetting and Xv. That's it. Though it would be fun to know if 3D still works, for things like UT99

    Oh, you have an i810? I kinda wish I had that, just to play around with. As far as I know, this is the situation:

    - concerning modesetting, there's no KMS, but X should have the correct resolution. no idea about dual-screen, probably not supported
    - concerning 2D, there's only XAA, which is useless nowadays, so you're basically without acceleration. you do get Xv for video playback, at least that
    - concerning 3D, there is a kernel DRM module and a DRI1 driver. the intel manpage says only 16bit is supported, but no idea if even that still works

    Sorry your right it was of cause mesa and not Xorg that doped the DRI1 drivers. However not enabled by default and in -dev doesn't count as working in my book, but its good to see that it is being worked on
